ABOUT THE
JAGUAR AJ126 ENGINE
The AJ126 is Jaguar Land Rover's 3.0-litre supercharged V6 petrol engine, in production from 2013 to 2020. It shares a 90° V6 architecture with the larger AJ133 5.0-litre V8 and was introduced as a high-performance six-cylinder option across Jaguar's range. The engine appears in the F-Type sports car, the XE and XF saloons, and the flagship XJ. The same supercharged V6 design was used across multiple JLR models, though its application-specific ancillaries, mounting and ECU calibration vary by model and year.
JAGUAR AJ126
APPLICATIONS BY MODEL
The F-Type was the launch platform for the AJ126, appearing in the V6 (340 hp), V6 S (380 hp) and 400 Sport (400 hp) variants throughout the X152 generation from 2013 to 2020. The XE adopted the same engine for its S and 300 Sport variants (X760, 2015-2019), offering a more sporting saloon option in the range. The XF followed with S and 35t variants (X260, 2015-2018), while the XJ applied the supercharged V6 to its Supersport V6 model (X351, 2013-2019) in markets where a six-cylinder option was preferred over the larger V8.
JAGUAR AJ126
ENGINE COMPATIBILITY
Because the AJ126 spans four different Jaguar models - F-Type, XE, XF and XJ - each with different mounting, ancillaries, and ECU calibration, compatibility comes down to confirming your exact model, generation, and year, which we do by registration/VIN. A supercharged V6 from an F-Type isn't a direct match for one from an XJ, even though it's the same base engine code. Ancillaries, mounting, and supercharger tune vary by model and year. Before we quote or supply anything, we confirm your exact vehicle.

OUR WORKSHOP VIEW OF
THE JAGUAR AJ126
Built, rebuilt and tested by engineers who work on Jaguar engines every day.
Here's our practical view of the AJ126 across its F-Type X152, XE X760, XF X260, XJ X351 applications.
APPLICATIONS WE SEE:
The AJ126 appears across four Jaguar model lines - F-Type, XE, XF and XJ - making it one of the broader-application V6 engines we work on.
WHAT WE REPLACE:
Timing chain components, bearings, gaskets, and supercharger coupler as standard on every rebuild, with vehicle-specific ancillaries accounted for per application.
KNOWN ISSUES:
The AJ126 has documented timing chain stretch patterns - the same tensioner and timing chain problems as the larger AJ133 5.0 V8, though less frequent and typically appearing at higher mileage. Supercharger coupler wear is also a documented source of rattling noise, and cooling system leaks from pipes, hoses and connectors are a known failure point on higher-mileage examples.
AJ126 REBUILD INFORMATION
Typical rebuild scope:
A TYPICAL
JAGUAR AJ126 REBUILD
The following describes a typical rebuild scope for this engine - illustrative of the work involved, not a specific customer job. Real case studies from our own completed work will replace this section once available.
The AJ126 shares timing chain issues with the larger AJ133 V8. We inspect the timing system thoroughly on every rebuild, with particular attention to tensioners and guides. The supercharger sits on top of the engine and must be removed to access critical components in the valley where the oil cooler and timing chain are located. Plastic coolant pipes and connectors are known failure points and are inspected during strip-down.
01INSPECTION & STRIP-DOWN
Careful inspection of the crankshaft, cylinder head, and timing chain components during strip-down.
02COMPONENT REPLACEMENT
Main bearings, connecting rod bearings, gaskets, seals, and timing chain components replaced as required.
03QUALITY CHECKS
All major rotating assemblies, oil pump, and cooling system components inspected for long-term reliability.
Typical Scope:
Timing chain, bearings, gaskets, supercharger coupler, cooling system inspection
Starting From:
£3,200

JAGUAR AJ126 REBUILD VS REPLACEMENT VS USED
Rebuilding Your AJ126 Engine
Most engine suppliers sell you a used engine of unknown history and hope it matches. We rebuild the engine your Jaguar already has instead - strip it down, pressure-test it, and replace every worn or damaged component with updated OEM parts. You get a near-new engine with a 12-month unlimited-mileage warranty, without the compatibility risk of an unknown used unit. This is the option most Jaguar owners choose, and it's the one we'd recommend for most situations.
- Strip down & inspect
- Pressure-test
- Replace worn components
- 12-month unlimited-mileage warranty
Replacement AJ126 Engines
If your existing engine is beyond economical repair, we also offer full engine replacement and fitting - sourced and fitted by our team, with the same 12-month unlimited-mileage warranty.
- Supplied & fitted by our team
- OEM quality
- 12-month unlimited-mileage warranty
Used AJ126 Engines
In some cases, a matched low-mileage used engine is the right call - particularly if you need your car back on the road quickly and your existing engine's damage is extensive. We can source and fit these too, though most owners who ask about used engines end up choosing a rebuild once they understand the compatibility risk a used unit carries, especially given how many different AJ126 applications exist across the Jaguar range. Enter your reg below and we'll talk you through both options honestly.
- Low-mileage units
- Quick turnaround

Reconditioned, Refurbished or Remanufactured?
JAGUAR AJ126 RECONDITIONED ENGINES
"Reconditioned" is the term many owners search for when they mean the same thing as a rebuild - a full strip-down, inspection, and replacement of worn parts rather than a straight swap. If that's what you're after, our rebuild service is exactly that.
→ Our rebuild service is exactly that.
JAGUAR AJ126 REFURBISHED ENGINES
"Refurbished" often describes the same process from a different angle - restoring your existing engine to full working condition rather than replacing it outright. Our rebuild covers this.
→ Our rebuild service covers this.
JAGUAR AJ126 REMANUFACTURED ENGINES
Some owners specifically search for a "remanufactured" engine, expecting a unit rebuilt to original specification with updated components. That's consistent with what our rebuild service delivers, regardless of which of the four AJ126-equipped models you drive. AJ126 Reconditioned, Refurbished & Remanufactured Engines Terminology Explained: Rebuilt: Existing engine stripped, inspected and rebuilt to original specification. Reconditioned: Broad industry term; we define our rebuild as a full strip and rebuild. Remanufactured: Usually implies a defined restoration process; our rebuild meets this standard. Used: Existing engine from another vehicle; we can source and fit these. What Jaguar Garage Means by "Rebuild": Full strip-down, inspection, measurement, machining where required, replacement of worn components, reassembly, testing, and refit - with a 12-month unlimited-mileage warranty.
→ That’s consistent with what our rebuild service delivers.
